MUSIC-BOX.

SPECIFICATION forming part of Letters Patent No. 391,505, dated October 23, 1888.

Application filed February 4, 1588. Serial No. 263,018.

To aZZ whom it may concern.-

Be it known that I, EMILE BORNAND, of Ste. CroiX, Switzerland, have invented certain new and useful Improvements in Music-Boxes, of which the following is a full, clear, and exact description.

The invention relates to music-boxes with interchangeable cylinders; and the obj eet of the invention is provide certain new and useful improvements in music-boxes by which the cylinders can be easily and accurately placed in position in the box and quicklyinterchauged whenever desired.

The invention consists of a mainspring-case provided with a gear-wheel meshing into the pinion of the wind-wheel, and also provided with a second gear-wheel meshing into a pinion on the cylinder-shaft.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of a music-box provided with myimprovement. Fig. 2 is a longitudinal sectional elevation of the same on the line :10 a: of Fig. 1. Fig. 3 is a vertical crosssection of the same on the line y 3 of Fig. 1,

' and Fig. 4 is a like view of the same on the line 2 z of Fig. l. l

The music-box A is provided with the usual comb, B, on which operates in the usual manner the cylinder 0, of any approved construction, and carrying on its shaft D the pinion E, meshing into the gear-wheel F, formed on the mainspring-case F of the driving mechanism G, of any approved construction, and serving to impart the usual rotary motion to the said shaft D and its cylinder 0, which is mounted to slide on and to rotate with the shaft D. On the mainspring-case F is also formed a second gear-wheel, F meshing into a pinion, F connected in the usual manner with the windwheel or regulator F", of any approved construction.

The cylinder-shaft D, as well as the windwheel F*, are thus operated on simultaneously by the rotation of the mainspring-case F of the driving mechanism G, and when the said (So model.)

spring-case F and wind-wheel F" are stopped or started in the usual manner by the ordinary stop-lever, F, then the cylinder-shaft D and its cylinder 0 are also stopped or started. The gear-wheel F and the pinion E have such a relative number of teeth that one revolution of the mainspring-case F causes three revolutions of the cylinder 0.

The shaft D is provided with two round bearing parts, H and I, one near each of its ends, and the flattened parts J and K, of which the part J is extended by a ing, L, as shown. The shaft D is held to rotate with its round bearing parts H and I in the hearings N and O, respectively,which are secured in the usual manner to the main frame, and each of which is provided with an inclined slot, P, leading to a round bottom slot, P, in which the round bearing parts H and I of the shaft D rotate. On the bearing 1? is also formed a circular recess, I concentric with the round bottom slot, P, and into the said circular recess P projects the inner end of the lug L, to prevent this end of the shaft D from wabbling.

On the shaft D, next to the flattened part K, is formed a collar, Q, on the inside of the bearing 0, and on this collar Q operate, between it and the bearing O, the wedgeshaped prongs R R, secured to the arm S, pivoted at S- on the bearing 0, and provided at its front end with a handle, S", for conveniently operating the said arm. \Vhcn the arm S is pressed down, the prongs P R straddle the shaft-D at the flattened part K, so that the shaft is prevented from moving upward. On the pivoted end of the arm S is formed a wedgeshaped lug, S", adapted to operate on a lug, T, formed on the repeating or changing lever T, so that the latter is thrown out of contact with the usual repeating and changing mechanism located on the cylinder O whenever the said arm S is moved backward in order to change the cylinder and its shaft.

On the ends of the shaft D are formed the knobs or buttons U and U, respectively, serving to handle the shaft conveniently in moving it, with the cylinder O, to and from the bearings N and 0. On the button U presses a spring, V, serving to move the shaft 1) longitudinally in its bearings N and O in the direction of the arrow (1. The slots P are some what narrower than the diameters of the bottom slots, P, so that when the round parts H and I are engaged in the said bottom slots, P, the cylinder cannot be lifted out of the bearings N and O. i

The operation is as follows: The lug L on the shaft D is placed in such a position in relation to the cylinder 0 that when the latter stands at rest at the end or beginning of a piece of music with the comb the said lug L and flattened parts J and K of the shaft D are in line with the inclined slots P in both bearings Nand 0. When the driving mechanism G is at rest, the several parts are in the position shown in the drawings, and when the operator now desires to change the shaft D and its cylinder 0 for one of like construction, with the exception of different pieces of music being on the cylinder, he throws the arm S backward, so that the prongs R disengage the shaft D and the collar Q, and at the same time the lug S presses the pin T backward, whereby the lever T is thrown out of contact with the changing and repeating mechanisms on the cylinder 0. The spring V press ing on the shaft D causes the latter to slide longitudinally in the direction of the arrow a, so that the pinion E is disengaged from the gear-wheel F of the driving mechanism G, and the round bearing parts H and I of the shaft D are disengaged from the round bottom slots, P, of the bearings N and O, and the flattened parts J and K now enter the said bottom slots, P, the lug L entering the inclined slot P of the bearing N. The operator now takes hold of the knobs U and U and lifts the shaft D upward and out of the bearings N and 0 through the inclined slots P. A shaft of like construction and provided with a cylinder having different pieces of music on its rim can now be inserted by placing the flattened parts J and K in the inclined slots P, with the lug L on top. hen the shaft rests in the bottom slots, P, the operator moves the arm S forward and downward, so that the wedge shaped prongs R straddle the shaft D, and at the same time the wedge-shaped parts of the prongs press against the face of the collar Q, whereby the latter, with the shaft D and the cylinder 0, is moved longitudinally in the inverse direction of the arrow a until the flattened parts J and K of the shaft D have left the bottom slots, P, and the round bearing parts H and I have entered the said bottom slots, P, of the bearings N and O. The springV is thus compressed, and remains so until the arm S is again moved out of contact with the collar Q, as above described. The pinion E is moved into mesh with the gear-wheel F of the drivingmechanism G when the shaft D is moved in the inverse direction of the arrow at, as above described.

Thus it will be seen that the driving mechanism, the comb, and the changing and repeat ing devices are not at all disturbed while the changing of the cylinder takes place. The

whole arrangement is extremely simple and durable in construction, and the cylinder almainspring-case provided with a second gearwheel, of a wind-wheel operated by the said second gearwheel, substantially as shown and described.

5. In a music-box, the combination, with slotted bearings, of a shaft having flattened parts adapted to pass into the slots of the said bearings and an arm for moving the said shaft longitudinally, so that the flattened parts are disengaged from the said bearings, substantially as shown and described.
